Lots of marquee performers are in the area this week - Kesha, Bob Dyland and Leon Russell, a bunch of djs at the traveling music festival IDentity. But the signature event of the week is clearly the annual Rap Round Robin, which this year will feature performances by AK Slaughter, Rap Dragons, Mickey Free and Height. Also this week: in addition to Bill Cosby, who will be at Pier Six, Martin Lawrence will also be in town, performing at 1st Mariner Arena.

On Tuesday, Bob Dylan performs at Merriweather Post Pavilion, 10475 Little Patuxent Parkway , Columbia. The show would be a best bet with Dylan on his own, but the legendary Leon Russell is opening for him. 6 p.m. Tickets start at $40.
